"Exhaust Fan + Cooling Pad" Cooling System - the most economic coolingsystem working principle: In a closed house, the cooling pad and the fan are always oppositely arranged, and the cooling pad is installed on the wall surface facing monsoon wind. When need air cooling, start the fan to force out of air inside the house, forming negative pressure in the house. At the same time, the water pump spray water onto the cooling pad wall, and outdoor air will be inhaled by negative pressure. In the process of inhaling, outside hot air flow through the cracks of cooling pad at a certain speed, leading to evaporation and cooling. Then cold air flow through the house, absorbing heat in the house, and then exhausted out by fan, so as to achieve cooling purpose.
